The body is not flattened horizontally like that of the first rib. Its external surface is convex, and looks upward and a little outward; near the middle of it is a rough eminence for the origin of the lower part of the first and the whole of the second digitation of the serratus anterior; behind and above this is attached the posterior scalene ...
Visceral and viscus (from Latin viscera 'internal organs'): associated with organs within the body's cavities and pertaining to the innermost layer. [57] For example, the stomach is covered with a lining called the visceral peritoneum, as opposed to the parietal peritoneum. Viscus can also be used to mean "organ". [57]
The smaller middle part of the ligament connects to the intervertebral disc. This plane joint is known as the articulation of the head of the rib . The other costovertebral joint is that between the tubercle on the neck and the transverse process of the corresponding thoracic vertebra, known as the costotransverse joint .
The organs, muscles, and other contents of the torso are supplied by nerves, which mainly originate as nerve roots from the thoracic and lumbar parts of the spinal cord. Some organs also receive a nerve supply from the vagus nerve. The sensation to the skin is provided by the lateral and dorsal cutaneous branches.
This article contains a list of organs in the human body. It is widely believed that there are 79 organs (this number goes up if you count each bone and muscle as an organ on their own, which is becoming a more common practice [1] [2]); however, there is no universal standard definition of what constitutes an organ, and some tissue groups' status as one is debated.

Superficial anatomy of female and male human body Surface projections of the major organs of the trunk, using the vertebral column and rib cage as main reference points of superficial anatomy Superficial anatomy or surface anatomy is important in human anatomy being the study of anatomical landmarks that can be readily identified from the ...
The term “flat bone” is something of a misnomer because, although a flat bone is typically thin, it is also often curved. Examples include the cranial (skull) bones, the scapulae (shoulder blades), the sternum (breastbone), and the ribs. Flat bones serve as points of attachment for muscles and often protect internal organs.
Surface projections of the major organs of the trunk, using the vertebral column and rib cage as main reference points of surface anatomy. Surface anatomy (also called superficial anatomy and visual anatomy) is the study of the external features of the body of an animal. [1] In birds, this is termed topography.
